So can you do it.

Yes you can.

Should you do it is the bigger question.

So my first question would be what type of drives are you using? Enterprise class drives with a low failure rate?

Doesn’t matter. From my experience: With 2x replication you will loose data at some point.

As a consultant I have just seen too many cases of data loss with 2x.

Please, don’t do it.

I'd like to ask: do the new features like checksumming fix this problem?
